Pretty much all game developers wait to do serious optimization until it is almost complete. Doing otherwise means a lot of wasted time redoing optimizations every time you add our change something. This is no different and won't really be any more challenging than it is for any other game. Yes, voxels may add some more difficulty but you are otherwise in the same boat as any developer in any game.The game is very poorly optimized due tot the fact there is 13 years of coding to deal with and no plans to do real optimizations tell its beta.
Toss in the fact it's a voxel based game and it gets bad on even the best hardware.
Better hardware can make this less painful but not a great experience.
It's a alpha game so this is hardly unexpected though and we shouldn't be too surprised.
Single player is not great but playable but the multiplayer is a train wreck at this point.
When it does come time to optimize i wouldn't want to be the Dev's as waiting so long to do so is going to leave them with a nightmare mess to deal with and possible one they can't fully fix.

That said, I can play the game at 60fps even during blood moon and on almost ultra settings (motion blur are disabled because I hate that and a few others are reduced simply because I really don't care about them and see no reason to have them high). I also run the graphics at 1080p and not 4k. And I have an older computer... AMD Ryzen 5 2400 with Radeon RX 580 GPU. After updating to 32GB RAM and installing a Samsung 870 EVO SSD, I get the really good fps. The times it drops are only when certain textures that have a lot of detail or shadows are focused on. This is true even in MP, though I don't use a server. It is even true when I host others.
Now, I'm not saying the game is optimized well. However, considering they haven't really gotten into optimization too much yet, it is pretty good. Of course, everyone will have different experiences, especially with servers, and this is just what I have seen.
The biggest improvement was really the SSD. I had the game installed on SSD, but my OS SSD is tiny and so I had the page file on my HDD. With low RAM and using a slow page file, I typically got fps in the 20s or even lower. The biggest hits were in the tier 5 cities. With the new SSD, I can have my page file on SSD (it's on my tiny M.2 SSD and the game was moved to the new SATA SSD). So even though the game is on a slower SSD, the page file on the fast SSD made a huge difference. Adding the extra RAM completed the improvement for me. I haven't seen it drop under 40fps even with a lot of really textured blocks being focused on and almost all the rest of the time it's a steady 59-60. It isn't perfect by any means but I also don't have a great computer. This was a low end gaming PC 4+ years ago and my only improvement to it was RAM and another SSD.That gives me some hope. I am thinking of updating to 32GB ram and an an ssd. I can play the game pretty well with what I am using now but thought doing that might help. With my settings most times I get around 60fps.
This gives me another slight nudge toward pulling the trigger on ram and ssd.
I will hopefully soon be running 64GB DDR5 4800 (stock speed for the motherboard) and my OS on a 1TB M.2 PCIx 4.0 NVMe and Steam on a 2TB M.2 PCIx 4.0 NVMe. I know this is not much of an upgrade from my 32GB DDR4 3000 and PCIx 3.0 NVMe M.2s, but the Intel Core i7-13700K and RTX 4070Ti should make the most difference.The biggest improvement was really the SSD.
